To all whom it may concern:

Be it known that I, ISAAC ylDIvIs, of Fitzwilliam, county of Cheshireend State'of New Hampshire, have invented e new and Improved Cartridge,of which vthe following is e spefdeetionr Figure 1 is elongitudinal-section of my improved cartridge. Fig. 2 is an end view ofthe sections. ,if A

The object of m55/invention is to accelerate the motion of pvojeotilesby dividing the. charge of explosive, so that leach successive portionof the chelrge increases the velocity of the projectile in erithmeticelproportion.

In the drawing, a b c are sections of the cartridge-shellrwhich areconnected by the plugs d, which are. provided with nipples c, upon whichpercussion-'oeps f ere placed. A bell., g, also having a rnipple, e, andprovided with e oep, f, is iittedl to the last of the series ofcnrtridge-shell sections. l

The section a is provided with the ordinary percussion-head h, and whenthe cartridge is charged with powder and discharged in the.

' usual way, the charge in the `section a moves the plug between thesections a. b forward, so

that it strikesthe percussion-cap f on the nip-, ple of' the secondplug, which explodes the charge contained by the second section, b, and

moves the second plug forward until it strikes f the, cap f on thenipple projecting from the belly, and causes thetlrird chargetoeiqilode.4 The second plug moves with doublethe velocity of the rst,and the bell moves with double the velocity of the second plng, or fourtimes that of the rst.

There are various ways ot' exploding the several charges, and the formofthe cartridge maybe varied from that shown and described 5.

therefore I do not confine myself to the exact construction herein setforth..

' Having thus'fully described my invention, 1

claim es'new end desire to secure by Letters Iatent- A cartridge havinge shell made in two or fmore sections, connected by plugs, and eachcontaining seperate charges of explosive, the 1 plugs and bullets beingprovided with nipples for receiving percussion-cops, substantially as'shown and described.
